1 Claim.

This invention aims to provide a novel device, adapted to be assembled with a tractor, and to be used for cutting wood.

It is Within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made Within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings:

Fig. 1 shows in top plan, a device constructed in accordance with the invention;

Fig. 2 is a side elevation;

Fig. 3 is an elevation disclosing the opposite side of the .device from that depicted in Fig. 2;

Fig. 4 is a front elevation;

Fig. 5 is an elevation showing the buzz saw and parts which cooperate with it;

Fig. 6 is a section on the line 66 of Fig. 5;

Fig. '7 is a fragmental cross section taken approximately on the line '|-1 of Fig. 1, parts being omitted;

Fig. 8 is a section taken on the line 88 of Fig. 1. a

The numeral I marks a tractor, including parallel frame members 2, the tractor comprising a power driven pulley 3, for the operation of a belt 4.

A supporting frame F is provided, and includes rails 5 and 6, disposed parallel to the frame members 2, and outwardly thereof. Inwardly projecting transverse brackets 1 are held by securing elements 8 on the rails 5 and 6, the inner, upright portions of the brackets carrying hook bolts 9 engaging the frame members 2 of the tractor The rails 5 and 6 are joined together by a front cross piece Ill. The cross piece I is connected to the rail by an inclined brace II, the cross piece being connected to the rail 6 by diverging braces I2.

Standards I4 are secured to the rails 5 and 6.

The rear cross piece l5 .may be in the form of an elongated box, adapt- The cross piece I5 ed to carry tools or the like. is strengthened and reenforced by transverse ties I6 assembled with the upstanding front and rear walls of the cross piece l5.

Bearings I! are mounted on the rails 5 and 6,

directly in advance of the cross piece I0. A transverse arbor I8 is journaled for rotation in the bearings IT. A fly wheel I9 is secured to one end of the arbor I8 and is located outwardly of the rail 5. Inwardly of the side rail 5, a pulley is secured to the arbor I8, the pulley receivrear cross piece I5. The bracket 22 carries a ing the belt 4. The belt 4 extends through one of the brackets I. A buzz saw 2| is secured to the arbor I8, and is located outwardly of the rail 6.

A bracket 22 is secured to the rail 6, abaft the curved head 28 disposed against the outer side of the rail 6. An offset arcuate guide 29 has its ends secured at 30 to the head 28.

The numeral 3| marks a hand lever,.preferably made of wood. The lower part of the hand lever 3| is received between metal straps 32.. The bottom parts of the straps 32 are brought together to form a tongue 33, mounted on a pivot element 34 carried by the lower part of thehanger 21.

The straps 32 are attached by securing elements 35 to the hand lever 3|. One of the side straps 32 passes between the guide 29 and the hanger 21, as shown in Fig, 6, the lever 3| having a recess 36, receiving the guide 29.

The straps 32 are backwardly extended, to form rectangularly .disposed supports 31 for the piece of wood 38that is to be sawed.

When the lever 3| carries the wood 38 against the saw 2|, the wood is severed, the saw being rotated by a train of parts including the arbor I8, the pulley 20, the belt 4, and the power driven pulley 3 of the tractor The device is simple in construction, but it affords an eflicient means whereby a wood sawing instrumentality may be assembled with a tractor, novel means being provided for carrying the woodinto and out of engagement with the saw.

Having thus described the invention, what is claimed is:

A Wood. sawing mechanism comprising side rails, means for securing the rails to a tractor frame, a saw supported for rotation on one rail,

a depending hanger mounted on one rail, a transverse guide on the hanger, a hand lever, straps secured directly to opposite sides of the lever, the upper portions of the straps being continued. to form transversely projecting supports, the Width of the lever being such that the sup- HOWARD THIES.
